Magnification refers to increasing the size of an image or object.

It is commonly used in optics, like microscopes or lenses, to enlarge small details.

Explanation

Work is done when a force causes displacement of an object in the direction of the force.

A man pushing against the wall, although force is applied, the wall does not move, so no displacement occurs → no work is done.

Explanation

• The wavelength of a transverse wave is the distance between two adjacent crests or troughs.
• It is a fundamental property of waves.
• It is typically denoted by the symbol λ (lambda).

Explanation

• Pneumatic Technology deals with the use of compressed air to transmit power, control machines.
• It perform various tasks, such as powering tools, actuators, and pneumatic conveyance systems.

Explanation

Explanation

• The atmosphere is a thick layer of air that surrounds the Earth.
• This protecting it from harmful radiation and supporting life.
• It is composed of 78% nitrogen, 21% oxygen, and trace amounts of other gases.

Explanation

Step 1: Use projectile motion

The maximum range of a projectile (ignoring air resistance) is given by:

R=v^2sin(2θ)/g​

The maximum range occurs when θ=45∘the value is maximum at (i.e.,sin(90∘)=1).

Step 2: Plug in values

• $v = 12 text{m/s}$

• g=10 m/s^2

R=12^2⋅1 ​/ 10 

= 144/10

​=14.4 meters
